Brian Cox reveals how the beauty and order in earth’s cosmic backyard was formed from nothing more than a chaotic cloud of gas. Chasing tornados in Oklahoma, he explains how the same physics that creates these spinning storms shaped the young solar system. Out of this celestial maelstrom emerged the jewel in the crown, Brian’s second wonder – the magnficent rings of Saturn.

On an ice-choked lagoon in Iceland, he sees the nearest thing on Earth to Saturn’s rings, and using the latest scientific imagery and breathtaking graphics, he explains how the intricate patterns round Saturn are shaped by the cluster of more than 60 moons surrounding the planet.
